Should I return my X4? I can get 20€ from the 104€ back without returning it, plus it comes with a case and screen protector. It’s the Chinese version, and I’ve been frustrated with the app. Is this a good deal, or would the reTerminal, Stiky, or PaperNano from M5Stack be better? I also have both Waveshare e-ink and RLCD for testing and put some firmware on it, so I’m not sure. It’s like getting the X4 Pro with an orange case and screen protector for 80€. I already have my Kindle 10th gen for reading, so I could use the 104€ for another deal, like the Bigme B6 or something with Linux and fast refresh.

Should one contribute to the GDP Win Max 3 crowdfunding campaign immediately, or consider waiting before making a decision?

I'm worried about the cost. If the prices are going to rise or if they're going to keep them the same or offer discounts, that would be great.

Hey r/RTLSDR & r/SDR! 👋 I’m xyz‑rainbow, and I’ve been building xyz‑sdr, a Python TUI SDR controller that works with any SoapySDR device (RTL‑SDR, HackRF, Airspy, SDRplay, etc.).

Here’s what it looks like (FFT + Waterfall + Timeline fully synchronized): [Demo xyz-sdr] - https://github.com/user-attachments/assets/6bf02f3e-dbbf-41fc-9be9-94ce2defc04c

What main features xyz‑sdr does today

• Loadable band profiles (FM, Airband, PMR446, HF‑LSB, etc.)
• Bookmark system for save frequencies
• Demod modes: WBFM, NBFM, AM, USB, LSB, CW, DSB, RAW, "auto"
• Band scanner while RX is active
• IQ bandwidth presets 250 kHz → 8 MHz
• DROP‑rate indicator + debug mode Simulation mode (run the full TUI with no hardware): run.ps1 --sim

Im using this stack; python 3.9–3.12 · SoapySDR · pytest/pytest-cov · TOML config primary: Windows 10/11 (with DX packaging + installer scripts) Linux/macOS: scripts/run.sh (works, less polished — help welcome!)

I'm looking for collaborators and Hardware testers,

Especially: HackRF, SDRplay, Airspy
(But anydevice helps) Even without hardware, -Sim mode lets you run the TUI without any hardware and see the app working with simulation audio. Linux/macOS testers — the shell launcher works but I haven't tested nothing on those OS :( DSP contributors — demod pipeline is functional but minimal; FM stereo, NFM, AM demod improvements are needed asap TUI contributors: If you know Python, curses, urwid, textual, or just enjoy terminal UI work you’re welcome. Any feedback — bugs, missing features… UX, missing band profiles etc.. it needs much works, its the first version

Thanks!
